More than 1 billion brand new 100 dollar bills slated to be released next year have been quarantined because of a printing problem. The bills that have been rendered useless, have a creasing problem on one of its edges that when unfolded, reveals a blank portion on the bill where a security ribbon should be. The new design was supposed to make them more resistant to counterfeiting.

The error puts the February 2011 release date in jeopardy. Each bill costs 11.8 cents to print which amounts to $120 million in lost production costs. The notes have not been put into circulation, and are sitting in lockup in Fort Worth, Texas and Washington, D.C. CNN's Christine Romans explains.

After the storm, most ATMs were down because there was no power. It quickly became a cash economy. CNN's Jeanne Meserve reports on how IOUs worked for one bank.
